Castleman's disease is a rare entity with an unknown etiology which was first described by Castleman in 1954. It is a lymphoproliferative disorder histologically classified into three types; hyaline-vascular, plasma cell type and mixed type. It might be localized or multicentric and usually involves the mediastinum. We report a case of Castleman's disease discovered accidentally in a case of blunt chest trauma which caused a challenging diagnostic process and management.

Pulmonary hydatid disease remains a significant health problem in endemic areas including Saudi Arabia. Different surgical tactics and approaches are still a subject of discussion. Here, we present a case of bilateral pulmonary hydatid cysts with spontaneous rupture that underwent successful one-stage bilateral enucleation and capitonnage.
